Abstract

An on-board electrical powered regeneration system for vehicles propelled by an electric traction motor and having an electrical storage cell bank composed of a rotatable flywheel operatively connected to an impeller, a fuel combustor arranged to emit a stream of gas directed to impinge on the impeller, a supply of fuel for the combustor, a generator driven by the flywheel, and electric power control means connected between the generator and the cell bank to convert the electrical output of the generator to a form compatible with the cell bank. Use of the flywheel as a power retainer and booster is also disclosed.

Claims

1. In an electrically operated wheeled vehicle having an electric traction motor powered by an electrical energy storage cell bank, driving at least one vehicle wheel, a powered regeneration system comprising in combination:

a. a rotatably mounted flywheel;

b. an impeller operatively connected to said flywheel;

c. a fuel combustor arranged to emit a stream of combustion gas directed to impinge on said impeller to rotate said flywheel;

d. a supply of fuel for said combustor;

e. an electrical generator operationally connected to said flywheel to produce electrical power upon the rotation of said flywheel; and

f. electrical power control means connected between said generator and said cell bank to recharge said bank upon the operation of said generator.

2. The apparatus of claim 1 wherein said electrical power control means comprises an electrical storage capacitor network and/or an AC/DC converter.

3. The apparatus of claim 1 wherein said fuel comprises hydrogen peroxide and said combustor comprises catalytic fuel ignition apparatus.

4. The apparatus of claim 1 wherein said impeller comprises a plurality of paddle extensions fixed about the circumference of said flywheel in spaced apart relationship.

5. The apparatus of claim 1 further including clutch means operatively connected between said flywheel and said vehicle wheel, said clutch means operable upon braking of said vehicle whereby power is transferred from said vehicle wheel to said flywheel upon braking of said vehicle, said transfer resulting in rotation of said flywheel.

6. The apparatus of claim 1 wherein said vehicle has at least one rear wheel, and said apparatus further includes second clutch means operatively connected between said flywheel and said rear wheel whereby power is transferred from said flywheel to said wheel upon operation of said second clutch means.
